title: Isolated right posterior bile duct injury following cholecystectomy: report of two cases.
abstract: Anatomic variations of the right biliary system are one of the most common risk factors for sectoral bile duct injury (BDI) during cholecystectomy. Isolated right posterior BDI may in particular be a challenge for both diagnosis and management. Herein we describe two cases of isolated right posterior sectoral BDI that took place during laparoscopic cholecystectomy. Despite effective external biliary drainage from the liver hilum in both cases, there was a persistent biliary leak observed which was not visible on endoscopic retrograde cholangiogram. Careful evaluation of images from both endoscopic and magnetic resonance cholangiograms revealed the diagnosis of an isolated right posterior sectoral BDI. These were treated with a delayed bisegmental (segments 6 and 7) liver resection and a Roux-en-Y hepaticojejunostomy respectively with good outcomes at 24 and 4 mo of follow-up. This paper discusses strategies for prevention of such injuries along with the diagnostic and therapeutic challenges it offers.
